If you run multiple Facebook accounts, proxies are not optional — they are the difference between accounts that survive and accounts that get checkpointed on day one. Here is what actually matters when choosing proxies in 2026.
Why proxies matter
Facebook links accounts by IP and device. Log into several accounts from the same IP and they get associated — one ban can cascade to all of them. A clean proxy per account keeps them isolated.
Proxy types (best to worst for Facebook)
- Mobile (4G/5G) — highest trust; IPs are shared by real users so Facebook is lenient. Best for valuable accounts.
- Residential — real ISP IPs, high trust, a great all-rounder.
- ISP / static residential — residential IPs hosted in datacenters; fast and stable for long sessions.
- Datacenter — cheapest but easiest to detect; use only for low-value or throwaway tasks.
Rules that keep accounts alive
- One proxy per account. Never share an IP across multiple accounts.
- Match the country. Use a proxy from the same country as the account — e.g. a US proxy for a USA account.
- Keep it sticky. Don't rotate the IP mid-session; sudden IP jumps look suspicious.
- Pair with an anti-detect browser so each account also has its own fingerprint.
Common mistakes
Cheap shared datacenter proxies, rotating IPs on every request, and mismatched geo are the top three account killers. Quality proxies cost less than replacing burned accounts.
